Application filed lid-arch 11, 1925. Serial No. 14,653.

My invention relates to what I will term a hinge joint for vehicle springs, the object being to provide a simple and eflicient construction that will lend itself to the use'of anti-friction devices, whereby the oscillation of the springs and the working of the joint will be noiseless, free and easy, and will require lubrication on only rare occasions. Another object of the present invention is to provide a construction that will facilitate the ready assembly and disassembly ofthe various pa In the drawings whichshow for illustrative purposes only preferred forms of-the invention:

Fig. 1 isa front elevation of a sprin end and the associated parts of the hinge earing therefor, certain parts being-shown in section;

Fig. 2 is a side elevation, partly in section' v Fig. 3 is aview of the underside of the. parts shown Lin Fig. 1; I

Fig. 4 is a fragmentary sectional view of p a modification. t

1 represents what is sometimes termed a horn, usually provided at the front and rear end of a vehicle frame; It may be assumed, in this instance,,that the horn 1 is the front end of one of the sills of the vehicle frame. 2-3 represent integral, lateralhub-like extensions on the end of the or otherwise rigidly fixed a bearing pin 5.

The ends of the pin '5 project,beyond the edges of the spring, so that they may coact with anti-friction devices. nular bearing tracks. for receiving antifriction devices, such as balls 8-8. 910

are caps adapted to the ends of the hubs 2-3 and which serve to hold the parts 3 67 respectively in place. 11-12 are split rings, which serve to hold the caps 910 respectively in place. 1415 conventionally represent dust protecting washers of any suitable construction, provided to prevent dirt from entering the bearing chambers at theendsoft epin5.. I

2'*---3 are passages or recesses in the lower ends of the pin 5 to pass therethrough, so that when the! pieces 6+7 areremoved by withdrawing'th'em from the hubs 2. 3,'the

6- 7 are andirection to cause the pin e'nds 5 to pass out through the passages 2=3*. Were it not for these clearance passages it would, of course, be necessary to drivethepin 5 out of, the eye in the end' of the spring 4 before the spring could be removed from the horn. By the present construction this act of driving the pin out is avoided and the act of assembling or disassembling is greatly facilitated.

In Fig. 4 I have shown a modification, in which the 'cap'for holding'the bearing piece 6 inplace is indicated at 9, the same be ing threaded into the hub 2, so that, by tuming said cap, it may be advanced and retracted, and thus the bearing ring 6 may be adjusted on the balls 8 to take up wear.

9" is a set screw, to hold the cap 9* in place sheet metalcup in which the dust ring 14 is fitted. The bottom of the cup may be\ I I apertured and threaded so as to permit a tool to be inserted for withdrawing the cup I 6 from the boss 2. If desired the aperture maybe closed as bymeans of aiscrewplug. 16 which, however, is readily removable to permit the bearing surfaces to be lubri-' catedi or to permit the use of the tool as above described. I

Iclaim: f V 1 1. In an-anti-friction bearing for a vehicle and in combination with a frame and spring, bosses on said frame and spaced apart. to

admit the end of the spring, a bearing pin secured in the spring'end and having ends projecting laterally beyond the sides thereof, said' bosses having recesses therein to receive said pin ends, one of said bosses having a lateral passage entering the recess therein to permit the introduction of the pin ends into said recesses, and anti-friction members for supporting said pin ends in said recesses. y

2.' In the combination definedlin claim 1, said other bow havingia lateral passage therein communicating with its-recess for permitting the passage of a pin en 3'. In an anti-friction bearingv vehicle and in combination with a vehicle frame and spring sse s on 'said frame and having recesses efein, a bearing in secured to-said spring and having en' s pro;

for. a""

jecting laterally beyond the sides thereofsaid recesses to permit the introductlon of said pin ends into said recesses."

4. As an article of manufacture, a vehicle frame having aligned bearing recesses therein spaced apart from each other, said frame having a lateral passage therein communicating with one of said recesses.

5. In an anti-friction bearing for a vehicle and in combination with'a frame and spring, said frame having spaced apart bearing recesses therein, said spring having anti-frich Ways carried b tion bearing member raceways thereon projecting laterally beyond the sides thereof,

.said frame'having a'lateral passage communicating with at least one of said hearing recesses for permitting the introduction of said anti-friction bearing member racesaid spring into said recesses, and ant -friction bearing members between said raceways and said caring recesses.

6. In the combination defined in claim 5, and complementary bearing member race rings in said bearing recesses to engage said. anti-friction bearing members. a

7. In the combination defined in claim 5, and removable closure members for the outer ends of said recesses in said frame.
